On 28 August 2015, Amorebieta returned to the Riverside Stadium for the entirety of the season, with Husband again being lent to Fulham for a month as part of the deal.[18] On 1 February of the following year, however, he was recalled.[19]

On 22 July 2016, Amorebieta returned to Spain and its top division after agreeing to a three-year contract at Sporting de Gijón.[20] He made his debut on 21 August, playing the full 90 minutes in a 2–1 home win against former club Athletic.[21]

As early as 2006, Amorebieta expressed his interest in playing for the Venezuela national team.[24] However, according to FIFA rules at the time, he should have switched his affiliation prior to the age of 21, having previously played for Spain's youth sides.[25] FIFA removed the rule in 2009,[26] and talks between the player and the Venezuelan Football Federation resumed.

Finally, on 2 September 2011, Amorebieta made his senior debut in a friendly with Argentina, a 0–1 loss.[27] On 11 October, against the same opponent but for the 2014 FIFA World Cupqualifying campaign, he scored in a 1–0 home win, which signified Venezuela's first-ever win against the Albiceleste in the tournament.[28]
